454Hi,
I have placed one display field in a form. I have override the context method to write code for filter. The filters works fine but when i tried clearing the ranges applied for the filter i am facing one error called " Query missing QueryBuildDataSource for FormDataSource SalesLine". Help me on this.
public void context()
{
int selectedMenu;
formrun fr;
Args ag;
Name strtext;
querybuilddataSource qb1;
queryrun qr;
query q;
PopupMenu menu = new PopupMenu(element.hWnd());
int a = menu.insertItem('Filter By Field');
int b = menu.insertItem('Filter By Selection');
int c = menu.insertItem('Remove Filter');
;
q = Salestable_ds.query();
qb1 = q.dataSourceTable(tablenum(Salestable));
qb1 = qb1.addDataSource(TableNum(Salesline));
qb1.relations(true);
selectedMenu = menu.draw();
switch (selectedMenu)
{
case -1: //Filter by field
break;
case a:
ag = new args('SysformSearch');
fr = new formrun(ag);
fr.run();
fr.wait();
//Reading User entered value for filter process
strtext = fr.design().controlName('findedit').valueStr();
if(strtext)
{
//Creating a query for filter
qb1.addRange(FieldNum(Salesline,CustAccount)).value(strtext);
Salestable_ds.query(Q);
Salestable_ds.executeQuery();
}
break;
case b: // Filter By Selection
qb1.addRange(FieldNum(Salesline,CustAccount)).value(customeraccount.valueStr());
//info(customeraccount.valueStr());
Salestable_ds.query(Q);
Salestable_ds.executeQuery();
break;
case c : // Remove Filter
q = new Query();
qb1 = q.addDataSource(tablenum(Salestable));
qb1.clearLinks();
qb1.clearRanges();
Salestable_ds.query(Q);
Salestable_ds.removeFilter();
break;
Default:
break;
}
}
Regards,
Ram
